Question

im using DOMDocuments to download an RSS feed into my PHP script, simple by:

$doc = new DOMDocument();
$doc->load($source);

I want to use instead of DOMDocument, CURL. How can change those 2 lines of code to make all my script compatible?. This is my complete script by the way:

<?php
//PUBLIC VARS
$arrFeeds = array();
$downItems = 0;
$time_taken = 0;
//*PUBLIC VARS
function getRSS($source) {
    $start = microtime(true);
    ini_set('default_socket_timeout', 1);
    global $arrFeeds, $downItems, $time_taken;
    $arrFeeds = array();
    $doc = new DOMDocument();
    $doc->load($source);
    foreach ($doc->getElementsByTagName('item') as $node) {
        $itemRSS = array ( 
            'title' => $node->getElementsByTagName('title')->item(0)->nodeValue,
            'desc' => $node->getElementsByTagName('description')->item(0)->nodeValue,
            'link' => $node->getElementsByTagName('link')->item(0)->nodeValue
        );
        array_push($arrFeeds, $itemRSS);
        $downItems+=1;
    }
    $time_taken = microtime(true) - $start;
}
//getRSS("http://www.atm-mi.it/_layouts/atm/apps/PublishingRSS.aspx?web=388a6572-890f-4e0f-a3c7-a3dd463f7252&c=News%20Infomobilita");
//echo(strip_tags($arrFeeds[0]['title'])."<br><br>".$time_taken);
?>

Thanks for the help!

This ought to do it:

$ch = curl_init($source);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$content = curl_exec($ch);
curl_close($ch);
$doc = new DOMDocument();
$doc->loadXML($content);

Your mileage may vary, of course, and you might have to add more CURL options, but that’s basic enough functionality to get it all started.
